Hi Ajay,
Greetings to you!

- I read your problem and implemented in Org. Please use the below code [Solved] : -
  
Component :  -

    <aura:component controller="findBiggestValueClass" implements="flexipage:availableForAllPageTypes,force:appHostable" access="global">
        <aura:attribute name="stringToSort" type="String" access="global"/>
        <aura:attribute name="BiggestNumber" type="String" access="global"/>
        <lightning:input label="Enter String to find biggest number (Separate values by comma)" name="stringToSort" value="{!v.stringToSort}"/>
        <lightning:button variant="brand" label="Find Biggest Number" onclick="{!c.findBiggestInteger}"/>

        <div class="slds-p-top_medium">Entered Text : - {!v.stringToSort} </div>
        <div class="slds-p-top_medium">Biggest Value : - {!v.BiggestNumber} </div>
    </aura:component>
    
JS Controller : - 

    ({
        findBiggestInteger: function (c, e, h) {
            console.log('In findBiggestInteger');
            let action = c.get("c.sortSlctRec");
            action.setParams({
                "stringToSort" : c.get('v.stringToSort'),
                });
                action.setCallback(this, function (r) {
                if(r.getState() === 'SUCCESS') {
                    let storedResponse = r.getReturnValue();
                    console.log('storedResponse:');
                    console.log(storedResponse);
                    c.set('v.BiggestNumber',storedResponse);
                } else {
                    console.log('ERROR');
                    console.log(r.getError());
                }
            });
            $A.enqueueAction(action);
        }
    })

Apex Class(Controller) : - 

    public class findBiggestValueClass {

        @AuraEnabled
        public static Decimal sortSlctRec(String stringToSort) {
            try{
                String sortString = stringToSort;
                List<String> sortList = sortString.split(',');
                List<Decimal> intList = new List<Decimal>();
                for(String s : sortList){
                    intList.add(Decimal.valueOf(s));
                }
                intList.sort();
                System.debug('intList--->'+intList);
                System.debug('intList--->'+intList[intList.size()-1]);
                return intList[intList.size()-1];
            }catch (Exception ee){
                System.debug('Error : -'+ee.getMessage()+' Line number-->'+ee.getLineNumber());
            }
            return null;
        }
    }

Hi Deepali,

Thanks for replying. As i was new to Apex ,I needed only a simple Apex class and a method which will accept a string of numbers and returning the Biggest number. I have modified the above code to the simplest as below:

 public class findBiggestValueClass {

      public static integer sortSlctRec(String stringToSort)
      {

              String sortString = stringToSort;

              List<String> sortList = sortString.split(',');

              List<integer> intList = new List<integer>();

              for(String s : sortList){

                  intList.add(integer.valueOf(s));

              }

              intList.sort();

             System.debug('The given List is :'+intList);

              System.debug('The Biggest number is :'+intList[intList.size()-1]);

              return intList[intList.size()-1];
         }

        }
    
  Now i need  a integer defining the value for n ? Like for 
eg:  if  n = 2  display first two biggest number in the List.



Thanks,
Ajay
